 Impact of Potassium Nutrition on Food Quality of Fruits and Vegetables: A Condensed and Concise Review of the Literature Among the many plant mineral nutrients, K stands out as a cation having the strongest influence on quality attributes thatdetermine fruit marketability, consumer preference, and the concentration of critically important human health-associatedphytonutrients. However, many plant, soil, and environmental factors often limit uptake of K from the soil in sufficientamounts to satisfy fruit K requirements during development to optimize the aforementioned quality attributes. This wasdemonstrated in a study reported in this publication in 2007 (Lester et al., 2007) where foliar K markedly improved severalcantaloupe fruit quality parameters, despite sufficient soil test K levels. This article expands on the previously reportedwork from the Rio Grande Valley of Texas by providing a review of published study abstracts on the effects of soil and/orfoliar K fertilization on several fruit and vegetable quality characteristics, including phytonutrient concentrations.

 World Fertilizer Nutrient Reserves—A View to the Future The stewardship responsibilities of agriculture include the wise use of the raw materials from which commercial fertilizers are produced. Development and implementation of fertilizer best management practices (BMPs) with focus on the 4Rs—right source, right rate, right time, right place—are timely not only for short-term economic and environmental reasons, but also for the wise stewardship of the non-renewable nutrient resources upon which food, feed, fiber, and fuel production depend. Read Full Story  Potassium Fertilizer Production and Technology The production, marketing, and application of potassium (K) fertilizers (potash) are essential for maintaining global food supplies. The new IPNI presentation on the potash fertilizer industry describes the major considerations in modern potash production and fertilizer technology. Read Full Story |
